With BobCAD-CAM V28, I just discovered something weird at the end of 2 axis profiling with contour ramping (for a circular contour).
If the "total depth" is not a multiple of "depth of cut", I get dangerous arc move at the end of the operation, just before the last arc move with constant Z.
For example, 2.1mm depth, depth of cut 0.25mm, here is the GCODE, with the weird move in red color:
NC Corrector display of the GCODECode:************* 64 - Feed moves//Arc move XY********** G17 G3 X-15.371 Y11.168 Z-2.100 R19.000 ************* 64 - Feed moves//Arc move XY********** G17 G3 X19.000 Y.000 R19.000 F552. ************* 64 - Feed moves//Arc move XY********** G17 G3 X-15.371 Y11.168 R19.000 ************* 50 - Rapid moves//Rapid move Z ********** G0 Z5.080 ************* 71 = Operations//End of operation ********** ************* 50 - Rapid moves//Rapid move Z ********** G0 Z25.400 ************* 5 - Ending blockes//End of program ********** O100 endif M5 M30
This move makes the tool colliding with the workpiece.
Not visible on BC display or in the simulation, as below.
So that looks like a postprocessor issue.
Any idea ?
Thanks.
